Error checking/warning if a source is inside a solid cell.

11.42.0.12 (July 27,2016)
Because of connections between the Plan View and Vertical Cross-section, if the Plan View is closed first, the program will crash. The problem has been corrected by having all Vertical Cross-sections created from a Plan View closed when that Plan View is closed.

11.42.0.11 (July 26,2016)
3D Scalebar size increased to make it more visible and plotted at max altitude.

11.40.0.13 (December 12,2013)
When multiple releases were present some distance/angles were with respect to the location centroid of all releases. Some were with respect to the selected release. Now all are with respect to the selected release location. The main viewport circle and distance circles can now be with respect to either the centroid or the selected release. The selection is made in the Options menu.

11.40.0.12 (November 8,2013)
Cumulative mass (total mass concentration) up to a given particle size can now be displayed in tables, 2D, and 3D. Previously, only the concentration at a given particle size was available.

When multiple processors were in use, the chemical reaction calculation could be incorrect for all but the chemical in the release description and could potentially crash CHARM.

11.3.0.8 (August 21,2011)
There was a bug in the CHARM sedimentation calculation. When very large particles (> few hundred microns) fall completely through a grid cell (e.g. with a vertical dimension of a meter) in a time step, the energy and momentum was not being conserved. The temperature in a cell would then be calculated as higher than it should have been resulting in a change in the dynamics of the plume. Mass was correctly conserved.
The maximum altitude reached by the solid cells in a grid is now reported on the main input screen in the grid section.

11.3.0.4 (May 10,2011)
In the Source Grid source term was used and particles are present with a size distribution, the particles were assumed to be the released chemical. They could not be set to be independent of the chemical.

Enhancement/correction in the advection/diffusion calculation. A "Phantom plume" could appear near grid edge for certain grids with certain meteorological conditions.

CharmEd editor for Site Information was modified to use a constant size font so that the text appears the same as in CHARM.
A correction was made in the Emergency Response mode when not using real-time meteorology. The program could go into an infinite loop if an update calculation took longer than one minute.

11.2.0.100 (November 30,2010)
The Surface Deposition Efficiency for vapor deposition has been enhanced to allow each species to have an efficiency for each land use surface type as imported in the Grid Editor.

A problem where map and release icons were improperly placed on Emergency Response and Plan View sub maps has been corrected.
The calculation for sedimentation velocities of particles has been further enhanced by using a continuous analytic expression rather than a table. The expression uses droplet density and surface tension in calculating the sedimentation velocity.

11.2.0.94 (October 30,2010)
Fall speeds for calculating deposition of particles has been enhanced to correctly handle very large particles.
Keyboard control of scrolling has been added. Arrow keys and Page Up and Page Down (Ctrl key for horizontal) will now scroll the display.

11.2.0.67 (July 26,2010)
Corrected a possible crash when creating a new display (e.g. 3D or particle deposition) if there are multiple sub grids.

11.2.0.66 (July 16,2010)
Correction to setting up the interpolation for determining the concentrations to use in the VCE calculation. Overpressures could be too high and the location of the actual maximum be incorrect by up to the difference of an explosion grid cell and dispersion grid cell.

11.2.0.64 (June 10,2010)
Correction so that large files (>4GB) are copied correctly.
